I typically see this error when the data was on the GPU but that data has since been lost from the GPU.

For example you can reproduce a similar error by simply doing the following:

x = gpuArray(1);

reset(gpuDevice(1));

disp(x)

Since you are training in deepNetworkDesigner I would check that your datastore does not contain gpuArray data and does not send data to the GPU. This should be unnecessary as trainNetwork will handle sending data to the GPU - and deepNetworkDesigner is using trainNetwork to do the training.

If this isn't the case could you post some code to show how you set up your datastore?
